ᕦʕ •ᴥ•ʔᕤ Bear Cub

Overview

🐻 A lightweight Hugo theme based on Bear Blog and Hugo Bear Blog.

Bear Cub takes care of speed and optimization, so you can focus on writing good content. It is free, multilingual, optimized for search engines, no-nonsense, responsive, light, and fast. Really fast.

Installation

Follow Hugo's quick start to create an empty website and then clone Bear Cub into the themes directory as a Git submodule:

git submodule add https://github.com/clente/hugo-bearcub themes/hugo-bearcub

To finish off, append a line to the site configuration file:

echo 'theme = "hugo-bearcub"' >> config.toml

Features

Like Bear Blog, this theme:

Is free and open source
Looks great on any device
Makes tiny (~5kb), optimized, and awesome pages
Has no trackers, ads, or scripts
Automatically generates an RSS feed

But that's not all! Bear Cub is also...

Accessible

Bear Cub has a few accessibility upgrades when compared to its predecessors. The color palette has been overhauled to make sure everything is readable for users with low vision impairments or color deficiencies, and some interactive elements were made bigger to facilitate clicking for users with a motor impairment.

These small changes mean that Bear Cub passes Google's PageSpeed test with flying colors.

Secure

Bear Cub's demo is hosted on GitHub and therefore I'm not in control of its Content Security Policy. However, the theme itself was made with security in mind: there are no inline styles and it uses no JavaScript at all.

If you want to improve your Mozilla Observatory score even further, you should be able to simply add a few headers to your hosting service's configuration (e.g. Netlify or Cloudflare Pages) and never have to think about it again. My _headers file, for example, looks like this:

/*
  X-Content-Type-Options: nosniff
  Strict-Transport-Security: "max-age=31536000; includeSubDomains; preload" env=HTTPS
  Cache-Control: max-age=31536000, public
  X-Frame-Options: deny
  Referrer-Policy: no-referrer
  Feature-Policy: microphone 'none'; payment 'none'; geolocation 'none'; midi 'none'; sync-xhr 'none'; camera 'none'; magnetometer 'none'; gyroscope 'none'
  Content-Security-Policy: default-src 'none'; manifest-src 'self'; font-src 'self'; img-src 'self'; style-src 'self'; form-action 'none'; frame-ancestors 'none'; base-uri 'none'
  X-XSS-Protection: 1; mode=block

Multilingual

If you need to write a blog that supports more than one language, Bear Cub has you covered! Check out the demo's config.toml file for a sample of how you can setup multilingual support.

By default, the theme creates a translation button that gets disabled when the current page is only available in any other language. You can also choose to hide this button (instead of disabling it) by setting hideUntranslated = false.

Every once in a while, as I keep using Bear Cub, I notice that there is some functionality missing. Currently, these are the "advanced features" that I have already implemented:

Full-text RSS feed: an enhanced RSS feed template that includes the (properly encoded) full content of your posts in the feed itself.
Static content: you can create empty blog entries that act as links to static files by including link: "{url}" in a post's front matter. You can also add render: false to your build options to avoid rendering blank posts.
Skip link: a "skip to main content" link that is temporarily invisible, but can be focused by people who need a keyboard to navigate the web (see PR #5 by @2kool4idkwhat for more information).
Reply by email: if you supply an email address, the theme creates a "Reply to this post by email" button at the end of every post (see Kev Quirk's original implementation).
Single-use CSS (EXPERIMENTAL): you can add some styles to a single page by writing the CSS you need in assets/{custom_css}.css and then including style: "{custom_css}.css" in the front matter of said page.
Conditional CSS (EXPERIMENTAL): since Bear Cub does syntax highlighting without inline styles (see config.toml for more information), it only load its syntax.css if, and only if, a code block is actually present in the current page.
Dynamic social card generation (EXPERIMENTAL): if you don't add preview images to a post, this template will generate one based on the title. You can see an example below.

Configuration

Bear Cub can be customized with a config.toml file. Check out the configuration of the demo for more information.

# Basic config
